Forking this discussion into a separate thread. Earlier today in the eGPU thread, SCSC posted: I'd like to understand what bugs actually remain in the latest drivers for the latest OS, so can anyone who knows of an issue please post about it here? Things we know about so far: - Performance "far below" Windows is just the typical Apple OpenGL vs DirectX comparison, and has nothing to do with NVIDIA (i.e. NVIDIA's Windows drivers are significantly better than everyone else's and thus the delta is greater). - iBooks uses Library Validation and thus Apple refuses to load the web driver binaries, though this might be fixed? There have been numerous OpenCL issues/crashes over the years but all the ones I've seen talked about here have been fixed in the latest drivers.
